Title: Tire for passenger car
Inventor: TAKINO HIROSHI
IPC: C08L9/06
Filed: 1988-02-23
Abstract: PURPOSE:To obtain a tire for a passenger car, excellent in steering stability, by using a tire treated made from a rubber composition prepared by mixing a specified rubber component with carbon black. CONSTITUTION:This tire for a passenger car has a tread made from a rubber composition prepared by mixing a rubber component comprising a styrene/ isoprene rubber of a styrene content of 5-40% and a styrene/butadiene rubber, a natural rubber or an isoprene rubber in a weight ratio of 5/95-60/40 with carbon black of an iodine adsorption (IA)>=100mg/g. In said rubber composition, about 50-200pts.wt. said carbon black of an iodine adsorption >=100mg/g is usually used per 100pts.wt. said rubber component. The iodine adsorption is measured according to JIS K6221, and when this amount is below 100mg/g, the improvement in the steering stability is small, while when it exceeds 250mg/g, it is not practical because of difficult workability in mixing.

Inventor: INOUE MASAYUKI
IPC: H02J3/01
Filed: 1992-01-29
Abstract: PURPOSE:To improve harmonic compensation effect by controlling an active filter through a signal from a control angle-harmonic current conversion circuit. CONSTITUTION:A control angle-harmonic current conversion circuit 3 generates a harmonic current signal with the magnitude and phase of harmonic which is previously generated in the manner of corresponding to each firing control angle. Then, an active filter composed of firing control angle determination circuit 2, phase inverter 8, hysteresis comparator 5, inverter 6, transistor Tr, injection circuit 9, etc., is controlled by a signal from this conversion circuit 3, and a harmonic current generated by this active filter is injected into a system line 1 to compensate harmonic current generated in a harmonic-generating load 1. Thus, it is possible to eliminate a time lag from the detection of load current to the determination of control angle to improve harmonic compensation effect.

Title: Method of operating dish washer
Inventor: YURA MASAKI
IPC: A47L15/48
Filed: 1989-02-20
Abstract: PURPOSE:To prevent the humidity of the inside of a wash tank from rising so as to disable a sufficient drying function from being obtained, by making heat-exchange between air having a high temperature and a high humidity inside of the wash tank and air having a normal temperature outside of the wash tank, and by operating a water discharge pump in accordance with a detection signal from a washing water temperature detecting means. CONSTITUTION:At a drying step, air having a high temperature and a high humidity is taken out from a washing tank 13 through an air-intake port 24 under operation of a fan A28 of a blower 27, and is then blown into the wash tank 13 through an air blow-out port 25 so as to be circulated, and simultaneously, the outside air is taken through an air-intake port 30 under operation of a fan B29 and is discharged through an exhaust port 31. In this phase, the air having a high temperature and a high humidity is heat-exchanged with the air outside of the wash tank 13. After the initiation of the drying step, a supply of water having a temperature higher than a predetermined value T3 is detected by a washing water temperature detecting means 33 which delivers a detection signal. A water discharge pump 16 is operated in accordance with the detection signal so as to continue the drying step. With this arrangement, it is possible to prevent a sufficient drying function from disabling from being obtained since a large quantity of steam is generated so as to lower the dehumidifying function.

As to the method for passivating the stainless steel, it is sufficient only by the level of immersing treatment process with concentrated nitric acid, or the like, and large-scale equipments are not required. For the further reduction of the amt. of scale generated, preferably the immersing time into concentrated nitric acid is prolonged, or passivating treatment is executed after final wire drawing.

Filed: 1989-02-20
Abstract: PURPOSE:To obtain a field effect semiconductor device free of irregularity of impurity concentration and region length by a method wherein, after a polysilicon layer surface is oxidized for a semiconductor substrate and then the oxidized part is eliminated, impurity is supplied. CONSTITUTION:A semiconductor substrate 1 to which impurity for forming a drain region 5 and a source region 6 is supplied is used] said substrate 1 is subjected to treatment for oxidizing the surface of a polysilicon layer 3. After an oxidized part 3a of the polysilicon layer surface is eliminated, a small amount of impurity is supplied, thereby forming a low concentration impurity region 5a for LDD (lightly doped drain) structure on the end of the drain region 5. In this case, the impurity concentration of the low concentration impurity region is determined only by the impurity amount supplied to the substrate surface. For example, it is easy to supply impurity to the substrate surface by ion implantation so as to exactly obtain a specified amount. Thereby, the irregularity of impurity concentration in the low concentration region can be reduced, and the irregularity of region length also is reduced.

Abstract: PURPOSE:To control a raw-material gas flow so that it is not disturbed and it does not come to contact with the wall of reacting tube and to make it possible to form a thin film by forming the raw-material gas flow which is jetted toward a substrate in the reaction tube into a beam shape with a control gas flow. CONSTITUTION:A raw-material gas flow 7 which is jetted toward a substrate 3 through a raw-material-gas jetting shower device 2 provided in a reacting tube 1 is surrounded with a gas flow which is jetted through a control-gas shower device 6. The gas flow 8 is formed with H2 gas and the like. The flow rate of the gas flow 8 is set at several tens of times the gas flow 7. The gas flow 7 is formed in a beam shape. The gap 9 between the wall of the reacting tube 1 and a susceptor 4 is made narrow so that the flow speed at this position is quick. Thus convection due to the heat of the substrate 4 is prevented. In this way, control can be performed so that disturbance is not generated in the stream of the raw material gas flow and the gas does not come to contact with the wall of the tube. Therefore, the high quality thin film can be obtained.
